Peshmerga critical of air-strikes strategy

Several months of US-led air strikes have pushed back the Islamic State in Iraq and the Levant (ISIL) in some areas, but the fighters have managed to advance elsewhere.

Kurdish Peshmerga forces are critical of the strategy behind the air campaign. Their commanders say they are not getting the support they need, and even accuse the US of having a certain "tolerance" towards ISIL's advance.

For his part, Haidar al-Abadi, Iraq's prime minister, has called for more air support. And in a Pentagon document addressed to Congress, the US says it will expand its influence in the battle against ISIL "with, by and through" Iraq's government.
